#define SYNTH_CLEAR   0x18 /* stops speech */

#define SYNTH_IO_EXTENT   0x02

#define TTS_ALMOST_EMPTY

Value:

0x04    /* mask for AE bit: When set to 1,
                     indicates that less than 300 bytes
                     are remaining in DoubleTalk's input
                     (TTS or PCM) buffer. AE is always 1
                     in the TGN and CVSD modes. */

#define TTS_ALMOST_FULL

Value:

0x08    /* mask for AF bit: When set to 1,
                     indicates that less than 300 bytes
                     are available in the TTS input
                     buffer. AF is always 0 in the PCM,
                     TGN and CVSD modes. */

#define TTS_READABLE

Value:

0x80    /* mask for bit which is nonzero if a
                     byte can be read from the TTS port */

Definition at line 6 of file speakup_dtlk.h.

#define TTS_SPEAKING

Value:

0x40    /* mask for SYNC bit, which is nonzero
                     while DoubleTalk is producing
                     output with TTS, PCM or CVSD
                     synthesizers or tone generators
                     (that is, all but LPC) */

#define TTS_SPEAKING2

Value:

0x20    /* mask for SYNC2 bit,
                     which falls to zero up to 0.4 sec
                     before speech stops */

Definition at line 8 of file speakup_dtlk.h.

#define TTS_WRITABLE

Value:

0x10    /* mask for RDY bit, which when set to
                     1, indicates the TTS port is ready
                     to accept a byte of data.  The RDY
                     bit goes zero 2-3 usec after
                     writing, and goes 1 again 180-190
                     usec later. */
